In next Tuesday’s episode of Fox’s comedy hit, Nick and Jess’ post-coital afterglow is darkened when her pop (the returning Rob Reiner) shows up on her doorstep unannounced. “They haven’t even had a chance to talk about it,” notes Reiner in the following sneak peek, “and then all of a sudden the father is thrust into the situation.”

As an added complication, Jess forbids Nick from breathing a word of their base-rounding rendezvous to her overprotective pa. “Keep your mouth shut,” she orders her lover. “He can never find out about this because he will kill you.”
